ADJUSTABLE WINDOW SCREEN. 7

Application filed February This invent-ion relates to improvements in windox'v screens of the laterallyad ustable type, an object being to provide a screen which may be retained within the lower again desired to use the screen, it must be either replaced in the guide groove for the lower sash, or, considerable space will be left between the upper portion of the screen and the bottom rail of the lower sash. Flies and other insects may then freely pass.

This and other disadvantages are overcome in the present invention by providing a screen which may at all times remain within the lower portion of the guide groove for the upper sash and conveniently moved into and out of position beneathv the lower sash without removing the screen from the groove and yet maintain such contact between the screen and sashjas to prevent the passage of insects. Y

With the above and other objects in View, the invention further includes the following novel features and details of construction, to be hereinafter more full described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a vertical sectional View showing a portion of a window with the screen positioned therein but not in use.

Figure 2 is a similar view showing the position of the screen in use. a I

Figure 3 is a. perspective View of the screen partly broken away.

Figure 4 is a fragmentary elevation of the upper part of thescreen.

. Figure 5 is an enlarged section on the line 55 of Figure 4.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character indicates a portion of a window frame in 1c, 1926. Serial no. 87,426.

whit-his slidingly mounted a lower. sash 11 and an upper sash 12, the former being slidable within the usual guide groove 13, while the upper sash is slidable within the usual guide groove 141-.v g

The screen comprises a pair of screen sections indicated at 15 and 16. These sections may be of any suitable construction, the section 15 including an upper rail 17 and a lower rail 18, while the section 16 includes an upper rail 19 and a lower rail 20. The rails 17 and 19, and 18 and 20 respectively are slidingly connected by any suitable means such as the tongue and groove connections indicated generally at 21 in Figure 5 of the drawings. As thus far described, the screen is of the usual laterally adjustable type which is removably positioned within the guide grooves for the sash.

The screen structure of the present invention includes a longitudinally adjustable sash engaging ledge which is offset with respect to the screen and which is designed to be engaged by the bottom rail of the. lower sash as shown in Figure 2 of the drawings. For this purpose, the upper rail 19 of the screen section 16 has secured thereto a longitudinally disposed strip 22. The upper rail 17 of the section 15 has secured thereto a transversely channel-shaped member ,23 which slidingly receives the strip 22. The outer end of the strip. 22 terminates just short of the end of the screen section 16, while the outer end of the channel-shaped member 23 terminates just short of the adjacent end of the screen section 15. By this means, the screen may be placed within the groove 14 of the upp er sash and the longitudinally adjustable ledge defined by the strip 22 and the channel-shaped member 23, and indicated generally at 24 in Figures 1 and 2 of the drawings, will extend inward beneath the lower rail of the lower sash with the ends of the ledge 24 abutting the strip S which separates the grooves 13 and 14. A continuous ledge is thus provided across the window so that thereis no opening or recess for the passage of insects. Normally, the screen is positioned as illustrated in Figure 1 of the'drawings and may be brought into use when the window is raised by pulling the upper portion of the screen inward as shown in Figure 2. A fin ger piece 25 is provided for convenience in positioning the screen.

It is preferred to provide the lower portion of the screen with spacing elements or blocks 26, one of which is positioned adjacent the outer lower edge of each screen sec tion so as to engage the outer walls of the guide grooves l l and hold the lower portion of the screen inward close to the strip S.

If desired, the member 23 may be provided with spaced openings 27 for the passage of a pin or other suitable fastening device to hold the screen sections in proper separated relation. 7

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is In a window screen device adapted to be mounted within the grooves of the upper sash of a window and to remain permanently therein, said screen device comprising laterally-slidably-adjustably connected screen sections including horizontal and vertical bars, the former being slidably connected and the latter being 'engageable within said grooves for the upper sash, a spacing block mounted at the lower edge of the screen and engageable with the outer wall of the groove for the upper sash, and a horizontal ledge at the inner face of the upper portion of the screen adapted to project into the path of movement of the lower rail of the lower sash for engagement thereby whereby" the screen device will be maintained in closing or obstructing relation to the space between the lower ledge of the lower sash, when the sash is raised, and the sill of the window frame.
